MCEC on WLC 9800s?

Do the new WLC 9800s support multichassis etherchannel? Would be helpful but not seeing that.

It is supported starting from IO-XE 17.2.1 upwards only. You can find more information on the below link.

You'll need to test your specific intended setup very carefully in the lab. For some reason they removed some of the standard LACP command options from IOS-XE which are supported on ASR1K so 9800 only supports a subset. Config we have which works on ASR1K (even older versions of IOS-XE) to ASR9K does not work with 9800 to ASR9K so we were forced to use a simplified design with reduced feature set. This problem bounced back between TAC and wireless BU for a while before they finally told us they don't support that and not in current roadmap to do so on 9800.

Good comments, thank you.

We will be connecting to VSS 4507 Core.

Have done Nexus 3172T with MCEC to same Core successfully.
